FreeOTFE4PDA is a free, open source, "on-the-fly" (OTFE) transparent disk encryption program. Using this software, you can create one or more "virtual memory cards" on your PDA - anything written to which will be automatically, and securely, encrypted before being stored.

· Source code freely available
· Easy to use; full wizard included for creating new volumes
· Data encrypted on your PC can be read/written on your PDA, and vice versa
· Powerful: Supports numerous hash/encryption algorithms, and provides a greater level of flexibility than a number of other (including commercial!) OTFE systems
· Hash algorithms include: MD5, SHA-512, RIPEMD-160, Tiger and many more
· Cyphers include AES (256 bit), Twofish (256 bit), Blowfish (448 bit), Serpent (256 bit) and many more
· "Portable mode" included; FreeOTFE doesn't need to be installed before it can be used - making it ideal for carrying your data securely on USB drives!
· Operates under both PC (MS Windows 2000/XP/Vista) and PDA (Windows Mobile 2003/2005) platforms
· Linux compatibility (Cryptoloop "losetup", dm-crypt and LUKS supported)
· "Hidden" volumes may be concealed within other FreeOTFE volumes, providing "plausible deniability"
· FreeOTFE volumes have no "signature" to allow them to be identified as such
· Encrypted volumes can be either file or partition based.
· Modular design allowing 3rd party drivers to be created, incorporating new hash/cypher algorithms
· Decryption software available to improve transparency, and allow even the most junior software engineer to prove data is being encrypted correctly
· Supports password salting (up to 512 bits), reducing the risks presented by dictionary attacks.
· Allows users to backup and restore the critical areas of volume files.
· Keyfile support included; store volumes and their associated metadata separately.
· Uses per-sector IVs, including support for ESSIV
· Volume file timestamps and attributes are reset after dismounting, increasing "plausible deniability"
· Supports volumes files up to 2^63 bytes (8388608 TB)
· Naturally, fully supported by SecureTrayUtil.
